Over the past month I've noticed that on ocassion, when i start my car, it idles as if not all cylinders are firing. A quick blip of the throttle and everything goes to normal. The weird thing is that it is idling at the same speed as usual. It has become more prominent this past week. Any suggestions would help.

 

Maybe a coil that's about to give away.

Any SES?

 

iacv or tb
maye even be a loose vacuum hose...

 

I had a similar thing, but a push of the throttle wouldn't take care of it. It would run like that for 10-15 minutes, then all the sudden was fine. It would happen every 3-4 weeks. The check engine light would usually stay on for a day or two, even after it was running fine. Never was able to get into the shop while the light was still on. Finally did and ended up having to replace the ignition coils.

Haven't had a problem since...
